WILLIAM SVINDELL, OF ALLEGHENY, PENNSYLVANIA.

GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent N o. 674,104, dated May 14, 1901.

n Application filed January 28,1901. serial No. 45.017. (No model.) v

T0 all whom vf may concern,.-

Beit known that I, WILLIAM SAWINDELL, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Gas-Pro ducers, of which improvement the following is a specification. i

The object of my invention is to provide a gas-producer in the` operation of whicha bet# ter and more uniform grade of gas may be generated than under prior constructions and a higher yield of gas may be obtained from the fuel employed.

. The improvement claimed is hereinafter fully set forth. l

In the accompanying drawings, Figure lis a vertical longitudinal section througha gasproducer, illustrating an application of my invention at thesline a o, of Fig; 2; Fig.' 2, a

horizontal section, through the same at the` line b b of Fig. 3, and Fig. 3 a transverse section at the line c c of Fig; 2.

In the practice of my invention the vertical walls 1 of the producer are, as heretofore, built of suitable masonry, preferably of substantially rectangular contour, as shown in Fig. 2, and inclose a centralchamber 2, which is covered and closed at its top by an arched roof 3, and which may be termed the gasdischarge chamber, and two or more lateral generating-chambers 11. shown four generatingchambers are employed, two being located on each side of the gas-discharge chamber; but a greater or less number may be adopted, in the discretion ofy the constructor, without departurefrom the spirit of my invention. l

The side walls of the producer are inwardly sloped or inclined from the lower ends of the generatingchambers (which, similarly tothe In the instance tending across the ash-pit to a level below that at which water may normally stand therein, as shown in Fig. 1.

Each of the generating-chambers llcommunicatesat a Vshort distance below its top o with the gas-discharge chamber 2 by a port 11a, which is controlled by a valve or door 11". .The doors of each pair of opposite generatingfchambers are preferably adapted to be coincidently operated in opposite directions-that isr to say,so that the .opening l movement of either one of them may be effected simultaneously with the closing Inoveme'nt of the other. To thisend the doors of each pair ofopposite chambers 11 are in the instance shown connected by rods or chains to the opposite ends of double-armedoperating-levers 11, which are pivoted centrally to suitable supports on thetop of ther producer.

`A fuel-supply opening is formed inthe top of each of the gasgenerating chambers, each of said openings being controlled by a suitablefeed-hopper l2, through which fuel may be charged into the chamber at proper inter-y vals, as in ordinary practice. The gas-discharge chamber 2 may also be provided with fuel-supply openings 13, controlled by feedhoppers 14.

v .8o Y -A discharge-passage l5, controlled by a' Y damper 18,`leads out of the upper. portion of thegas-discharge chamber 2 andextends Y y downwardly to a connection with one end of .a Water-trough 1.6, from the opposite end oflwhich a delivery-pipe 17 leads toa desired point ofv gasldelivery. vApipe 19 for the sup-` ply of a spray of water lor current of steam leads into the downward extensionofthe dis` charge-passage, and a pipe 21 is provided f orf the discharge of water frornthe outer endyof y Y the water-trough 16. A plate 22, which ex'-I tends across the water-trough toa level bef f v. low that of the pipe 21, serves to. prevent the Y I95v escape of gas through the latter. Tvhelarea for the passage of gas over lthe surface ofthe water in the trough may be varied, as desired,4 M by an adj ustableA partition or gate-20, yvvh'ichI may be raised and lowered,as desired, 'by the operator.' Tar, soot, and other products which pass with the gas from the producer are col- I oo lected in the water-trough, from which they are withdrawn from time to timethrough an opening controlled by a suitable valve or gate.

In the operation of the producer fuel is charged into and maintained in combustion in the generating-chambers ll, the solid residuum passing down and being supported on the grates 4. The gas generated by the combustion of the fuel in each of the generating-chambers passes through the port l1b thereof into the gas-discharge chamber 2 and thence through the discharge-passage 15 and water-trough 16 to the delivery-pipe 17. The charging of one generating chamber with fuel and the delivery of gas from the opposite chamber are alternately eected, the door llb of the former being closed and that of the latter opened during these operations.

The alternation of fnelcharging and gasdelivery, which is provided for by a construction substantially as herein described and shown, attains a substantially advantageous result in regard to thequalityand uniformity of production of the gas generated and also promotes the full utilization of the gaseous elements of the fuel.

I claim as my invention and desire to secure by Letters Patentl. In a gas-producer, the combination of a gas-discharge chamber, generatingcham bers located on' opposite sides thereof and having separate fuel-su pply openings, a fuel-support below and open to each of said chambers, valve-controlled ports establishing communication between the generating-cham bers and gas-discharge cham ber, and a discharge-pas sage leading out ofthe gas-discharge cham ber.

2. In a gas-producer, the combination of a gas-discharge chamber, generating-chambers located on opposite sides thereof and having separate fuel-supply openings, a fuel-support below and open to each of said chambers, means for coincidently opening communication between the gas-discharge chamber and one of the generatingchambers, and closing communication between the other generating-chamber and the gas-discharge chamber, and a discharge-passage leading out of the gas-discharge chamber.

3. ln a gas-producer, the combination of a gas-discharge chamber, generating-chambers located on opposite sides thereof and having separate fuel-supply openings, a fuel-support below and open to each of said chambers, ports establishing communication between the generating-chambers and gas-discharge chamber, doors or valves controlling said ports, a doublearmed operating-lever piv-` oted to a support on the top of the producer, and having its arms connected to the portdoors of two opposite generating-chalnbers, and a discharge-passage leading out of the gas-discharge chamber.

4f. In a gas-producer, the combination of a central gas-discharge chamber, generatingchambers located in pairs on opposite sides of the gas-discharge chamber, all ot' said chambers being open at bottom and each having a fuel-supply opening, grates supported upon the producer-Walls below the bottoms of said chambers, ports, each leading from the upper portion of one of the generating-chambers to the gas-discharge chamber, doors, each controlling one of said ports, means for operating the portdoo`rs of each pair of generatingchambers independently of the others, and a discharge-passage leading out of the gas-discharge chamber.
